Martina Hingis is still undecided about a return to the WTA Tour to play doubles, although she is considering teaming up with Lindsay Davenport. Hingis also said Tuesday in a conference call from England that she will play legends doubles with former partner Anna Kournikova at Wimbledon. Hingis is returning to play a full season of World Team Tennis this summer after a two-year ban for testing positive for cocaine in 2007. The former No. 1 player denied taking the drug but did not appeal the ban. http://sports.espn.go.com/sports/tennis/news/story?id=5289112
